As of now, no DSA driver uses a custom link mode validation procedure anymore. So remove this DSA operation and let phylink determine what is supported based on config->mac_capabilities (if provided by the driver). Leave a comment why we left the code that we did, and that there is more work to do. Signed-off-by:

As phylink gained generic support for PHYs with rate matching via PAUSE frames, the phylink_mac_link_up() method will be called with the maximum speed and with rx_pause=true if rate matching is in use. This means that setups with 2500base-x as the SERDES protocol between the MAC/PCS and the PHY now work with no need for the driver to do anything special. Tested with fsl-ls1028a-qds-7777.dts.

Drop the custom implementation of phylink_validate() in favor of the generic one, which requires config->mac_capabilities to be set. This was used up until now because of the possibility of being paired with Aquantia PHYs with support for rate matching. The phylink framework gained generic support for these, and knows to advertise all 10/100/1000 lower speed link modes when our SERDES protocol is 2500base-x (fixed speed). Signed-off-by:

These are Gen3 Aquantia N-BASET PHYs which support 5GBASE-T, 2.5GBASE-T, 1000BASE-T and 100BASE-TX (not 10G); also EEE, Sync-E, PTP, PoE. The 112 is a single PHY package, the 412 is a quad PHY package. The system-side SERDES interface of these PHYs selects its protocol depending on the negotiated media side link speed. That protocol can be 1000BASE-X, 2500BASE-X, 10GBASE-R, SGMII, USXGMII. The configuration of which SERDES protocol to use for which link speed is made by firmware; even though it could be overwritten over MDIO by Linux, we assume that the firmware provisioning is ok for the board on which the driver probes. For cases when the system side runs at a fixed rate, we want phylib/phylink to detect the PAUSE rate matching ability of these PHYs, so we need to use the Aquantia rather than the generic C45 driver. This needs aqr107_read_status() -> aqr107_read_rate() to set phydev->rate_matching, as well as the aqr107_get_rate_matching() method. I am a bit unsure about the naming convention in the driver. Since AQR107 is a Gen2 PHY, I assume all functions prefixed with "aqr107_" rather than "aqr_" mean Gen2+ features. So I've reused this naming convention. I've tested PHY "SGMII" statistics as well as the .link_change_notify method, which prints: Aquantia AQR412 mdio_mux-0.4:00: Link partner is Aquantia PHY, FW 4.3, fast-retrain downshift advertised, fast reframe advertised Tested SERDES protocols are usxgmii and 2500base-x (the latter with PAUSE rate matching). Tested link modes are 100/1000/2500 Base-T (with Aquantia link partner and with other link partners). No notable events observed. The placement of these PHY IDs in the driver is right before AQR113C, a Gen4 PHY. Signed-off-by:

The SYN flood message prints the listening port number, but with many processes bound to the same port on different IPs, it's impossible to tell which socket is the problem. Add the listen IP address to the SYN flood message. For IPv6 use "[IP]:port" as per RFC-5952 and to provide ease of copy-paste to "ss" filters. For IPv4 use "IP:port" to match. Each protcol's "any" address and a host address now look like: Possible SYN flooding on port 0.0.0.0:9001. Possible SYN flooding on port 127.0.0.1:9001. Possible SYN flooding on port [::]:9001.

Steen Hegelund says: ==================== net: Add support for sorted VCAP rules in Sparx5 This provides support for adding Sparx5 VCAP rules in sorted order, VCAP rule counters and TC filter matching on ARP frames. It builds on top of the initial IS2 VCAP support found in these series: https://lore.kernel.org/all/20221020130904.1215072-1-steen.hegelund@microchip.com/ https://lore.kernel.org/all/20221109114116.3612477-1-steen.hegelund@microchip.com/ Functionality ============= When a new VCAP rule is added the driver will now ensure that the rule is inserted in sorted order, and when a rule is removed, the remaining rules will be moved to keep the sorted order and remove any gaps in the VCAP address space. A VCAP rule is ordered using these 3 values: - Rule size: the count of VCAP addresses used by the rule. The largest rule have highest priority - Rule User: The rules are ordered by the user enumeration - Priority: The priority provided in the flower filter. The lowest value has the highest priority. A VCAP instance may contain the counter as part of the VCAP cache area, and this counter may be one or more bits in width. This type of counter automatically increments its value when the rule is hit. Other VCAP instances have a dedicated counter area outside of the VCAP and in this case the rule must contain the counter id to be able to locate the counter value and cause the counter to be incremented. In this case there must also be a VCAP rule action that sets the counter id. The Sparx5 IS2 VCAP uses a dedicated counter area with 32bit counters. This series adds support for getting VCAP rule counters and provide these via the TC statistic interface. This only support packet counters, not byte counters. Finally the series adds support for the ARP frame dissector and configures the Sparx5 IS2 VCAP to generate the ARP keyset when ARP traffic is received. Delivery: ========= This is current plan for delivering the full VCAP feature set of Sparx5: - DebugFS support for inspecting rules - TC protocol all support - Sparx5 IS0 VCAP support - TC policer and drop action support (depends on the Sparx5 QoS support upstreamed separately) - Sparx5 ES0 VCAP support - TC flower template support - TC matchall filter support for mirroring and policing ports - TC flower filter mirror action support - Sparx5 ES2 VCAP support ==================== Signed-off-by:

This adds a sorting criteria to rule insertion and deletion. The criteria is (in the listed order): - Rule size (largest size first) - User (based on an enumerated user value) - Priority (highest priority first, aka lowest value) When a rule is deleted the other rules may need to be moved to fill the gap to use the available VCAP address space in the best possible way.

Update affinity hints on cpu hotplug events 3. Introduce transmit packet steering (XPS) NOTE: If irqbalance is running, you need to stop it from overriding our affinity hints.
